Public bug reported: The Invalid email addresses section in the doctests in src/mailman/model/docs/registration.rst attempts to register various invalid email addresses and checks that they are rejected. In particular, the test >>> registrar.register(mlist, '\xa0@example.com') Traceback (most recent call last): ... InvalidEmailAddressError: \xa0@example.com will fail if python's sys.getdefaultencoding() returns 'UTF-8' because the invalid address is reported with the UTF-8 encoding of nonbreaking space rather than \xa0. ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1285496 Title: A test in src/mailman/model/docs/registration.rst fails if Python default encoding is UTF-8 To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1285496/+subscriptions
